Graduation of elements properties in the modern periodic table

The video tutorial demonstrates an experiment where coal is burned in a jar filled with oxygen, producing carbon dioxide. This gas is then dissolved in water, forming carbonic acid, which turns violet litmus solution red. The experiment illustrates how non-metals react with oxygen to form non-metal oxides, using carbon as an example.

What happens when coal is burned in the presence of oxygen?

Describe the process of adding water to carbon dioxide gas.

What is the effect of carbon dioxide gas dissolving in water?

How does the litmus solution change when carbonic acid is formed?

What conclusion can be drawn about non-metals reacting with oxygen?
